Ay mama, first trimester talaga yan ang hirap, a few of us went through the same thing kaya gets ko! Headaches, lower back pain, and cramping are pretty common sa early pregnancy dahil sa hormonal changes at physical adjustments, pero since ganito kalaki ang sakit mo, mas maganda talaga kung i-check mo sa OB mo para sure lang na lahat okay? Hindi lang baby, importante rin na you're not pushing through something na kailangan ng medical attention, especially pag intense na talaga.
